>The UTs problem is that it's not open and never was so content was never indexed. The only search you can do here is via limited search through the UT UI which while decent isn't anywhere as intuitive or flexible what you would get if the content was indexed through a search engine.
I would like to add a note to that mention confirming content is indexable since a few years. Since anonymous was allowed to the site, search engines were able to index as well using a direct route. They index everything that is public, thus the messages, but when a user clicks on a message from a Google search, the entire interface will load as this will come from a user and not a robot.
Dangerous bots are blocked but regular search engines are able to view and index the messages. That includes Google.
When the site was moved under Level Extreme, a resend of the entry pages was done, despite the fact Level Extreme was already indexed on a regular basis and search engines would have found their way into the messages. So, that accelerated the process to adjust the links to the Level Extreme site.
For example, if you try that search on Google, you will get a link to the message:
https://www.google.ca/?gfe_rd=cr&ei=AGxNWaqJGYLs8Afe9Z7YCg&gws_rd=ssl#q=Multiple+forms+in+a+single+ASPX+page+-+BIG+limitation&spf=1498246142401When you click on it, you will get the entire interface, including the message, in anonymous mode, if not logged, or into the user's mode if logged.
